Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power grids face challenges in maintaining stable reactive power levels, especially in dynamic and volatile environments with integrated alternative energy sources, where latency in controlling reactive power units exceeds 1 second, making it difficult to manage voltage variations effectively.
Innovation Solution
A method and device utilizing radio base stations, such as Integrated Access and Backhaul (IAB) nodes, to measure and stabilize reactive power levels by generating reactive power, offloading traffic, inactivating power-consuming components, or reporting to a supervising device, which can rapidly adjust operations to maintain grid stability, potentially using Machine Learning to determine actions.

Engineering Contradiction Analysis
1Reliability
If reactive power units are distributed in the power grid to provide reactive power at selected locations, then the voltage level can be maintained, but heavy investments are required and control latency exceeds 1 second
Solution Approach 1:
The radio base station autonomously measures electrical properties indicating reactive power levels and automatically performs actions to stabilize reactive power without requiring external control signals. This self-service mechanism eliminates control latency by making the base station its own controller, while also reducing investment in dedicated reactive power units by utilizing existing base station infrastructure.
2Stability of the object's composition
If reactive power units are deployed to stabilize reactive power levels, then grid stability is improved, but heavy investments and complex control infrastructure are required
Solution Approach 1:
The radio base station performs multiple functions: it provides wireless communication services while simultaneously measuring electrical properties and stabilizing reactive power. This multi-functionality eliminates the need for dedicated reactive power control infrastructure, reducing device complexity while maintaining grid stability through the base station's existing computational and measurement capabilities.
